Is there any way to set up a WordPress install in which the search box ONLY searches tags?
The typical installation searches words within the post, and that can bring up too many possibilities. I.E., if someone wants to find a post on the TV show "Friends", it would bring up every post that uses the word "friends." But by limiting to a tag search, it would be simple for people to find exactly what they're after. (This would be on a secondary installation of WordPress within my existing site, acting as a sort of wiki.)
